Sparse Linear Models applied to Power Quality Disturbance Classification
, 2015 Power quality (PQ) analysis describes the non-pure electric signals that are usually present in electric power systems. The automatic recognition of PQ disturbances can be seen as a pattern recognition problem, in which different types of waveform ...

European Eating Disorders Review, EarlyView.ABSTRACT Objective Recovery rates for adolescent anorexia nervosa (AN) remain poor, requiring creativity within the field to explore alternative treatment options. One novel, evidence‐informed approach integrates both family/parent and individual adolescent‐focussed treatment components, through an individualised developmental lens. This study aimed to
